Answer is y = x + 52
you can substitute x with x and substitute y with y
for example:
x = 2 y = 54
54 = 2 + 52
54 = 54
it’s true

Find the price-demand equation for a particular brand television when the demand is 20 TVs per week at $150 per TV, given that t

Alina [70]

Answer:

~ $150=50e^{-0.01()20}$

~ $p(100)=\$127.7$

Step-by-step explanation:

From the question we are told that:

Price of 20TVs per week $P_{20}=\$150$

Marginal price-demand function $p'(x)=-0.5e-0.01x$

Generally the The Marginal price function is mathematically given by

$p'(x)=-0.5e^{-0.01x}$

$p(x)=\int-0.5e^{-0.01x}$

$p(x)=50e^{-0.001x}+C$

Therefore the equation when the demand is 20 TVs per week at $150 per TV

$150=50e^{-0.01()20}$

Giving

$p(x)=50e^{-0.01x}+150-50e^{-0.01(20)}$

Therefore the Price when the demand is 100 TVs per week

$p(100)=50e^{-0.01(100)}+150-50e^{-0.01(20)}$

$p(100)=\$127.7$

How many non-square numbers lie between the 215to the power of 2 and 216 to the power of 2

Vaselesa [24]

There are 430 non square numbers that lie between $215^{2}$ and $216^{2}$ .

Given two numbers $215^{2}$ and $216^{2}$ and we are require to find non square numbers that lie between them.

Numbers can be consecutive numbers or non consecutive numbers. In our question we will find the consecutive numbers.

Square numbers are those numbers whos square is in a proper number means decimal should not be there.

First number= $215^{2}$

Second number= $216^{2}$

First we have to find the exact value of numbers by finding the square of these numbers.

First number=215*215=46225

Second number=216*216=46656

Numbers that lie between them=(46656-46225)-1

=431-1

=430

Hence 430 numbers lie between $215^{2}$ and $216^{2}$ .
